The ac Hall effect can provide valuable insights into the dynamics of an electronic medium. This has recently been demonstrated in the case of high-Tc superconductors [1,2]: Various theoretical models based on different scattering mechanisms agree that the anomalous frequency and temperature dependences of the Hall effect are closely intertwined, but they differ in their predictions about these...

The Hall response function of symmetric and asymmetric planar Hall effect devices is investigated by scanning a magnetized tip above a sensor surface while simultaneously recording the topography and the Hall voltage. Hall sensor geometries are tailored using a focused ion beam, in standard symmetric and asymmetric geometries. With this technique we are able to reduce a single voltage probe to ...

The emergence of lexico-grammatical productivity has been a central issue in the field of Second Language Acquisition (SLA). Ellis (2002) proposed that formulaic chunks of language are one resource for the learner to develop such productivity. This exploratory study sought to determine whether formulaic language chunks were observed in the oral production of three adult beginner learners of Eng...

In the context of list-coloring the vertices of a graph, Hall’s condition is a generalization of Hall’s Marriage Theorem and is necessary (but not sufficient) for a graph to admit a proper list-coloring. The graph G with list assignment L satisfies Hall’s condition if for each subgraph H of G, the inequality |V (H)| 6∑σ∈C α(H(σ, L)) is satisfied, where C is the set of colors and α(H(σ, L)) is t...

BACKGROUND Scotland has high levels of untreated dental caries in primary teeth. The Hall Technique is a simplified method of managing carious primary molars using preformed metal crowns (PMCs) cemented with no local anaesthesia, caries removal or tooth preparation. This study compared the acceptability of the Hall Technique for children, their carers, and dentists, and clinical outcomes for th...

The notion of a Hall matrix, associated with a possibly anisotropic conducting material in the presence of a small magnetic field, is introduced. Then, for any material having a microstructure we prove a general homogenization result satisfied by the Hall matrix in the framework of the Hconvergence of Murat-Tartar. Extending a result of Bergman, it is shown that the Hall matrix can be computed ...
